Ab Initio Evidence for the Formation of Impurity d(3z^2-r^2) Holes in Doped La_{2-x}Sr_xCuO_4
Jason K. Perry, Jamil Tahir-Kheli, William A. Goddard
Using the spin unrestricted Becke-3-Lee-Yang-Parr density functional, we computed the electronic structure of explicitly doped La_{2-x}Sr_xCuO_4 (x = 0.125, 0.25, and 0.5). At each…
The Antiferromagnetic Band Structure of La2CuO4 Revisited
Jason K. Perry, Jamil Tahir-Kheli, William A. Goddard
Using the Becke-3-LYP functional, we have performed band structure calculations on the high temperature superconductor parent compound, La2CuO4. Under the restricted spin formalism…
The ARPES Pseudogap and Anomalous Background of Underdoped BiSCO 2212 as Evidence for a Fermi Level Band Crossing
Jason K. Perry, Jamil Tahir-Kheli
We show that the unusual observations of a pseudogap in the normal state of underdoped Bi_2Sr_2CaCu_2O_8+delta (BiSCO) using angle resolved photoemission spectroscopy (ARPES) is co…
Electron Correlation and the c-axis Dispersion of Cu d_z^2: a New Band Structure for High Temperature Superconductors
Jason K. Perry, Jamil Tahir-Kheli
Previously we showed the major effect of electron correlation in the cuprate superconductors is to lower the energy of the Cu d_x^2-y^2/O p_sigma (x^2-y^2) band with respect to the…
The Importance of Static Correlation in the Band Structure of High Temperature Superconductors
Jason K. Perry
Recently we presented a new band structure for La(2-x)Sr(x)CuO(4) and other high temperature superconductors in which a second narrow band was seen to cross the primary band at the…
Electronic Structure of La1.85Sr0.15CuO4: Characterization of a Fermi Level Band Crossing
Jason K. Perry, Jamil Tahir-Kheli
We present the results of a new Hubbard model for optimally doped LaSrCuO. This model uses parameters derived from BLYP calculations on the cluster CuO6. It explicitly includes the…
